Caméras hyperspectrales

Hyperspectral imaging combines high-resolution spectroscopy with digital imaging. A spectral camera images a line of an object and provides the spectral information of each pixel of that line in the second dimension of the detector. A movement of the object or of the spectral camera allows the acquisition of very sensitive and spectrally resolved images. Corresponding software displays a 3D spectral cube of an object or displays spectral information of moving objects.

A hyperspectral camera set-up includes optics, an imaging spectrograph, a camera displaying the spectral information and a software package to display and calculate the results.

Our spectral cameras cover the full spectral range using CCD and CMOS detectors in the VIS and VIS/NIR range, InGaAs cameras in the near IR, MCT detectors in the shortwave IR and InSb and microbolometers for hyperspectral imaging in the thermal IR.

Hyperspectral cameras can be used directly in laboratory or process control applications or they can be integrated in complete imaging systems for pharmacy, food production or geology. Some are also built in airborne systems and unmanned aerial vehicles (UAVs).

The all-in-one hyperspectral imaging system SpecimIQ is a highlight of current developments.

Specim IQ is a real all-in-one hyperspectral imaging camera that allows the acquisition, application and result within a single camera in only one sequence. Specim IQ has the footprint of a regular photo camera. It is fully portable, equipped with a sensitive touchscreen monitor, SD memory card and batteries.

The cost-effective, compact FX10 camera works in the spectral range 400 nm to 1000 nm. It uses fast optics for high light throughput, high sensitivity, short integration times and a high signal-to-noise ratio. FX10 runs with a spectacular frame rate of 330 fps, using perfectly resolving 1024 spatial pixels and 224 spectral bands. By reducing the number of spectral bands, the frame rate can be pushed to 9900 fps. FX10 is available with either a high speed CameraLink interface or GigE output.

FX17 is a hyperspectral camera for the spectral range 900 nm to 1700 nm. It uses an InGaAs detector with a high spatial resolution of 640 pixels. FX17 is equipped with an F/1.7 Specim lens. It boasts high light throughput and features a high signal-to-noise ratio of 1000:1 and short integration times. Thus, there is basically no need for external illumination. FX17 has high frame rates of 670 fps full frame. It offers a high spectral resolution in 230 spectral bands. With the provided software development kit, the number of analyzed spectral bands can be reduced to achieve a frame rate of up to 15000 fps with four bands.

SPECIM has just launched a fast hyperspectral camera in the shortwave infrared range (SWIR 1000 - 2500 nm). The camera uses a new and unique high-resolution detector with 384 spatial pixels. It achieves a very fast frame rate with up to 400 frames per second in full frame mode. The camera is built with temperature-stabilized optics which provide great stability and high sensitivity during long acquisition runs even under changing ambient temperatures. Even for long term applications, only one white reference acquisition is necessary. The camera is truly indispensable for a lot of challenging applications like SWIR and NIR chemical imaging, phenotyping, and painting or geological applications.

In the medium-wave infrared (MWIR; 3 - 5 µm) band, thermal radiation of objects is used to detect and analyze their composition. Hyperspectral imaging in the MWIR provides highly interesting information, as a lot of widely-used materials have characteristic spectral signatures in this range. Specim’s MWIR spectral camera combines a high-end cooled detector based on InSb with a Specim imaging spectrograph of highest performance. The MWIR spectral camera comes with specially designed front lenses with highest transmission and low optical aberrations to ensure the best possible performance.

Hyperspectral imaging in the longwave infrared (LWIR) band offers new ways to identify and quantify even more materials based on their characteristic spectral signatures. Thermal LWIR spectral imaging covers the range 8 – 12 µm and is widely used to analyze chemicals, gases, minerals or atmospheric radiations. Specim is the first manufacturer to have developed push-broom devices for hyperspectral imaging in the LWIR. They use brand-new imaging spectrometers with reflective and refractive optics.
